Abstract: PURPOSE:To smoothen the extent of fitting with a spline hole or the like corre sponding to a spline shaft or the like at all times by installing an elastic body pressing a cylinder in the axial direction of the supporting cylinder and a cam groove, whose axial double ends are biased in the circumferential direction, in one side of both spline elements and a cam pin engaging this cam groove in the other, respectively. CONSTITUTION:An time of a spline hole 31 of a work 30 fitting in a spline shaft 32, if both teeth 31a, 31b collide with each other at a shaft ends, any movement of a cylinder 5 to the left checked, but a supporting cylinder 2 alone is moved to the left by an arm (A) as compressing an elastic body 16. If so, a cam pin 11 at the side of the supporting cylinder 2 shifts to the left in relation to a cam groove 7, so that the cylinder 5 moves in the circumferential direction with the supporting cylinder 5. With this movement, the work 30 is rotated in the circumferential direction with the spline shaft 32, and at a time when both the teeth 31a, 32a are engaged with each other, the work 30 moves toward the spline shaft 32 by dint of reaction force of the elastic body 16, thus the spline hole 31 of the work 30 is fitted in the spline shaft 32.

Title: Method for inspecting spot welding
Inventor: KOMAI TADASHI
IPC: G01N29/04
Filed: 1998-11-11
Abstract: PROBLEM TO BE SOLVED: To identify a nugget part and a corona bond part quantitatively and securely with improved reproducibility by judging cases where a transversal ultrasonic level is higher and lower than a reference level as the nugget and corona bond parts, respectively. SOLUTION: When an ultrasonic probe 50 enters a welded part, namely when the level of a first reflection wave (a longitudinal wave) of a lower plate 20 is larger than the level of a first reflection wave (a longitudinal wave: S wave) of an upper plate 10, a gate G is applied. The gate G is set with a proper interval such as t2/3 based on a time interval of t2 between the S wave and the first reflection wave of the lower plate 20. Then, the level of the reflection transversal on the bottom surface of the lower plate is measured for each fine scanning displacement of the ultrasonic probe 50. When the level drops temporarily and the increase after that is lower than a reference level, no nugget part 32 is formed although a welded part exists, and all are judged to be a corona bond part 34.  When the level drops temporarily and the increase after that is higher than the reference level extremely, it is judged that the nugget part 32 has been formed at the welded part.

Filed: 1990-11-27
Abstract: PURPOSE:To attain effective failure diagnosis to an abnormal situation by advancing inference in the direction of cause and researching the failure cause from the result of observation data and so on with qualitative inference based on qualitative causal relation. CONSTITUTION:When a qualitative relational expression on a parameter does not exist for an object model 4, it is recorded that the qualitative deviation of the parameter is possible to be the cause of failure and the effect is notified to a hypothesis control means 6. Then, the candidate of the causal parameter considered until then is destroyed and it is investigated whether the other candi date of the causal parameter exists or not. Then, when the other candidate does not exist, the hypothesis control means 6 is notified of the relational expres sion used for inference there is possible to be errorneous and the inference processing process is backtracked on to one step before it. Besides, when the other candidate exists, the processing on the other candidate is advanced. Thus, various abnormalities are failure-diagnosed effectively.

The carrier used is a magnetic carrier coated with a silicone resin. By using this carrier, the surface energy decreases to prevent melt sticking. Further, since the carrier has a low coefft. of friction and good fluidity, influences of the carrier toner on agitation in a developing device or pressing by magnetization on a regulating member for the amt. to be carrier and on the surface layer of a sleeve can be decreased. With decrease in the Van der Waals force with the toner and a developing sleeve, the carrier hardly deposits.
